Default Marvel Mystery Oil

I have an engine that last ran about 10 years ago. A while back I had heard good things about Marvel Mystery Oil. Now that I am thinking of using some in this engine I find that they have products for use in the oil and for use in the gas.

Need some advice on which to use on engines that haven't run for some time. Stories are always good.

Thanks for your help on this.
